The Empirical Assessment of Domestic Radicalization (EADR) project seeks to provide practitioners, researchers, and the public with an empirical foundation for understanding the radicalization processes of United States-based extremists. Project researchers utilized a mixed-method, nested approach to explore a number of key research questions related to radicalization, including: <ul> <li>what are the demographic, background, and radicalization differences between and within the different ideological milieus?</li> <li>are there important contextual, personal, ideological, or experiential differences between radicals who commit violent acts and those who do not?</li> <li>is it possible to identify sufficient pathways to violent extremism?</li> <li>are the causal mechanisms highlighted by extant theories of radicalization supported by empirical evidence?</li> </ul> To address these questions, EADR researchers built the largest known database on individual radicalization in the United States: Profiles of Individual Radicalization in the United States (PIRUS). The database includes 147 variables covering demographic, background, group affiliation, and ideological information for a sample of 1,473 violent and non-violent extremists who radicalized in the United States from 1948-2014. The database is not limited to a particular ideological milieu, but instead contains information on individuals who adhere(d) to far right, far left, Islamist, and single-issue ideologies The collection includes 5 SPSS datasets and 2 SPSS syntax files: <ul> <li>PIRUS_full_dataset_ICPSR_archive.sav (n=1,473; 113 variables)</li> <li>PIRUS_expected_maximization_version.sav (n=16,203; 27 variables)</li> <li>PIRUS_fixed_value_imputation_version.sav (n=1,473; 27 variables)</li> <li>PIRUS_regression_based_imputation_version.sav (n=16,203; 28 variables)</li> <li>PIRUS_subgroup_mean_substitution_version.sav (n=1,473; 27 variables)</li> <li>quantitative_analysis_syntax.sps</li> <li>variable_prep_syntax.sps</li> </ul>
